Decided to try this GFO after using rowaphos for the last couple years. the first thing i noticed was how quick this stuff rinsed out. took no time at all to flush. The price is good and so far no issues.

I started running BRS GFO about 1 year ago during a hair algae outbreak, and within a month, that problem was gone. Paired with the BRS reactor, and a monthly change of GFO, I haven't seen a strand of the green stuff since. It's a much more rewarding hobby when our tank is the envy of your fellow reefers!

Good price for the 1 gal container. Media run through a BRS reactor keeps my phospates at 0ppm. Just flush the fresh media with ~1 gal or less RO water until it runs clear to get rid of the "dust", then ready to roll.

I was looking for something to help with my saltwater algae problem and decided to try this and I have been extremely happy so far. I will say that I will be trying the higher capacity next because the space needed in a reactor is is greater in the standard GFO.

Perfect GFO. I use this product in conjunction with skimming, carbon dosing (pellets and sometimes biofuel) and carbon with great results. My parameters stay in range, and the recommended starter amounts seem to work well for most applications.

I can honestly say gfo has made my life easier. Without it, I'd probably have to do 2 water changes a week with my desire to feed as often as I do. I'd never have a tank without gfo in a reactor.

Great valueBy Steveon 10/20/2012

Nice value for GFO. Not as nice as the uniform spherical GFO you get with other premium brands, thus may not fluidize quite as easily, but gets the job done.

This is every bit as good as any other product on the market. I had been using phosban for years and decided to try this 6 months ago. well after 6 months phosphates are testing 0. What makes this more appealing is the price and quantity you get. There is nothing else like this in the market!

Works Great!By Tobyon 9/20/2012

Toby would recommend this product to a friend

Bought the granular (the cheaper of the 2) GFO's that BRS offers. I ran it in a Nextreef MR1 reactor and used the recommended amount from the BRS Reef calculator for GFO. It lasted 4 weeks (with heavy fish/coral bio-load). Phosphates dropped from 2.0 to 0.0 overnight. It stayed for about 3-4 weeks and began to creep back up so I removed it and increased the amount. Hoping to get 6 weeks out of it. I recently purchased the high capacity because I think it'll be a better fit for my system.

HC GFO is a better productBy Joshuaon 7/24/2012

Joshua would recommend this product to a friend

In terms of the quantity of phosphate removed, this GFO performs very well. I use it actively in a BRS reactor and had zero problems. However, it does produce more fines when initially flushing the media, and from what I've read, the high capacity stuff holds up better during regeneration because it is more dense.
